E TEXAS UTILTTIES SERVICES INC. INSTRUCTION REVISION PAGE ATTACHMENT 1 CP-EI-4.6-7 1 7-18-80 4 of 7 CMC FORM COMPLETION The Component Modification Card Form (CMC) (Figure 2 of Ref.1-A) is completed as follows.

a. Serial Number - Prenumbered or numbered through detailed application instructions as required.
b. Section 1, Application - State generic category of work.

Weld Mod, Q, Non-Q--Check appropriate block.

Design Change / Deviation--cross out changes -

or deviation, one which does not apply.

Enter "N/A if not a change or deviation to design,

c. Section 2, DWG No. - Enter the complete number and revision of the I affected design basis drawing (s).
d. Section 3, Line No/ Component No. - Enter the specific identification number of the component to be modified; hanger number or N/A as applicable, etc.
e. Section 4, Reason for change - State briefly but concisely the reason for change. If to implement a change previously approved by the original design; clearly state this fact; (e.g. to implement DE/CD 8600).
f. Section 5, Instructions - Describe completely and accurately the change to be made. Enter "N/A" in the

" Remove" & " Add" blocks.

I

g. Secticn 6 - Provide sketch indicating the existing and/or new l arrangement when necessary for clarificaiton (additional '

i. Section 8, Approved by - An authorized Field / Design Engineer shall approve the Change / Deviation. (See Section 2.3 of instructions)
j. Section 9, Distribution - See section 3.1.5 of instructions. If additional copies are designated in in Section 9, it is the responsibility-of the originating organization to re-produce and distribute the copies. These

. copies will be marked "For Engineering and Office Use Only."

REVISION TO CMC"5 Revision to CMC cards may be handled by the following two methods:

Method 1. Using Original Card - Copy of original CMC will be made prior to revision and will remain in DCC for his-orical reference. Original card may then be revised as required. In addition the following will be completed.

aa. The appropriate revision numcer shall be placed adjacent to the serial number.

bb. The CMC card shall contain the following state-ment:

"This revision voids and supersedes Document rNFO RMATION Serial number , Revision .

/

E} Using New Nonserialized Form - Complete new fom per C r D

2.

above instructions with following addition:

Ry 1. Use same serial number as original and apply revision number per aa.

2. Write statement per bb.

VOIDING CMC'S When an occasion ariseo where a CMC has been issued and is for some reason is not needed, it must be voided.

To void a CMC, the original card must be revised in accordance with Method 1 above with the exception of statement per bb. Instead the CMC shall clearly be marked " Void - not superseded."
